The Alsto Impact Test Apparatus is based on the crushability test (CWi) that was developed by F.C. Bond. The impact apparatus consists of two pendulum-mounted hammers, each weighing approximately 30 lb, and mounted to simultaneously strike equal blows on opposite sides of each rock specimen. The crushability test is to be performed on ten or more representative pieces of broken stone. Each is to pass a 3-in. square opening and be retained on a 2-in. square opening. More specimens will increase the reliability of the test results.
